SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Swift projects increasingly rely on concurrency features like actors and MainActor, but incorrect usage leads to data-race bugs and unsafe code. This Skill provides a structured method to identify concurrency issues, align code with Swift 6.2 approachableConcurrency patterns, and implement safe fixes with minimal behavioral changes.

Core Features & Use Cases

Triage concurrency problems by inspecting actor isolation, default actor behavior, and Sendable boundaries across the codebase.
Apply safe, minimal fixes such as annotating with @MainActor, creating isolated conformances, and using nonisolated/@concurrent strategies to offload work appropriately.
Leverage reference materials and migration guidance to align projects with Swift 6.2 concurrency best practices and improve robustness and performance.

Quick Start

Run a targeted concurrency audit on Swift files and apply minimal actor-isolation fixes.

FAQPage Schema

How do I fix data race safety issues in Swift 6.2 actor isolation code?▼

Swift concurrency migration to 6.2 involves triaging actor isolation and Sendable boundaries, then applying safe minimal fixes like @MainActor annotations and nonisolated strategies to align with approachableConcurrency patterns and improve robustness.

How do I audit Swift concurrency usage for actor isolation and Sendable boundaries?▼

Auditing Swift concurrency usage requires inspecting actor isolation, default actor behavior, and Sendable boundaries across the codebase. This triage identifies unsafe concurrent access before applying minimal fixes to align with Swift 6.2 best practices.

Does this Swift concurrency audit tool work with existing @MainActor and actor isolation patterns?▼

Yes, this Swift concurrency audit works directly with existing @MainActor and actor isolation patterns. It analyzes code for actor contexts and main actor defaults to validate safe edits without introducing behavioral changes or data races.

What's the best way to apply Swift 6.2 approachableConcurrency patterns without changing behavior?▼

The best way to apply Swift 6.2 approachableConcurrency patterns safely is using nonisolated and @concurrent strategies to offload work appropriately. This approach aligns projects with best practices while ensuring minimal behavioral changes.

Why does my Swift concurrency migration introduce data race bugs?▼

Swift concurrency migration introduces data race bugs when actor isolation and Sendable boundaries are incorrectly configured. Triage default actor behavior and apply isolated conformances or @MainActor annotations to validate no data races are introduced.
